Understanding cryptocurrency tax regulations in Bulgaria is relatively straightforward. The country applies a 10% flat tax rate on capital gains from Bitcoin and other cryptocurrencies, classifying them as financial assets. Bulgaria’s 10% rate represents one of the lowest flat-tax frameworks for digital assets within the European Union, aligning with broader crypto tax by country 2026 trends across Europe.

Overview of Crypto Tax in Bulgaria

In Bulgaria, individuals pay a flat 10% tax on cryptocurrency gains. There is no specific, separate legislation for digital assets; instead, the National Revenue Agency (NRA) applies general tax rules. The NRA treats all cryptocurrencies equally, whether it is Bitcoin, Ethereum, or other altcoins. This approach reflects a simplified distinction between capital gains vs income tax, depending on whether profits come from trading or activities like mining and staking.

As cryptocurrency adoption continues to grow (with approximately 13% of the population owning digital assets based on recent surveys), Bulgaria maintains a clear and EU-aligned approach for 2025–2026.

Key rule: Simply holding cryptocurrency is not a taxable event. Taxation only occurs upon disposal or trading.

Real-world example: If an investor buys Bitcoin for €50,000 and sells it for €70,000, the €20,000 profit is subject to the 10% tax, resulting in a €2,000 tax obligation.

Taxable Events for Bitcoin and Cryptocurrencies

Capital Gains from Selling or Trading

Selling cryptocurrency for fiat currency (like Euros or Leva) or exchanging one cryptocurrency for another triggers a taxable event. The NRA views this as the disposal of a financial asset. The taxable profit is calculated by subtracting the purchase cost from the sale price. These scenarios are part of broader crypto tax triggers and rules explained, which help investors determine exactly when tax obligations arise.

For crypto-to-crypto trades, the tax is based on the market value of the assets at the time of the transaction. Taxpayers generally use the FIFO (First-In, First-Out) method to accurately calculate their costs.

Mining and Staking Rewards

Income generated from mining or staking activities is also subject to taxation. When a user receives block rewards or staking yields, these are classified as taxable income at the standard 10% rate. The tax is based on the fair market value of the coins on the specific day they are received.

For example, mining 0.1 BTC with a market value of 5,000 BGN will result in a 500 BGN tax liability.

Holding vs. Professional Trading

Long-term holding without selling or exchanging does not incur any taxes. However, individuals who trade frequently with high volumes and a professional setup may be classified as business entities by the NRA.

While casual investors pay the standard 10% personal income tax, professional traders might be subject to a corporate tax rate of up to 15% and may need to register a formal company.

Tax Rates and Calculations

The taxation framework in Bulgaria is primarily built around a 10% personal income tax on net gains for individuals. For registered businesses, the tax rate is typically 10%, but can reach 15% depending on the specific company structure and activity level.

Furthermore, pure cryptocurrency exchange transactions are exempt from Value Added Tax (VAT), as they are considered financial services. However, businesses exceeding 100,000 BGN in annual turnover must register for VAT.

Reporting and Filing Requirements

Taxpayers must declare their cryptocurrency gains annually. The deadline for submitting the annual tax return (Form 200) for the previous year’s income is April 30.

It is mandatory to maintain detailed records of all transactions for up to five years. This includes purchase and sale dates, fiat values (in BGN), and wallet addresses. Failing to report crypto income can result in penalties, with fines reaching up to 10,000 BGN.

Tip: Using cryptocurrency tax software or exporting CSV files from trading platforms can help automate FIFO calculations and generate the necessary reports for the NRA.

Deductions and Exemptions

Bulgarian tax law allows investors to deduct certain costs related to their cryptocurrency activities. Taxpayers can subtract exchange fees, transaction (gas) costs, and the initial acquisition price from their total revenue to determine the net taxable gain.

Additionally, capital losses from cryptocurrency can be used to offset capital gains from other financial assets. However, there is no tax-free allowance or minimum threshold for small profits; all realized gains are taxable.

Example: If an investor makes a 5,000 BGN profit but incurs 1,000 BGN in fees and deductible losses, the taxable amount is 4,000 BGN. The 10% tax on this amount would be 400 BGN.

Compliance Tips for Bulgarian Crypto Investors

To ensure compliance with NRA regulations and avoid audits or fines, investors should follow these practices:

1. Use tracking tools: Implement software applications to automatically sync with wallets and exchanges to maintain accurate, continuous records.
2. Keep manual logs: Beginners should start a detailed spreadsheet recording the date, asset type, and BGN value of every transaction.
3. Consult professionals: For large portfolios or complex trading setups, speaking with a certified Bulgarian tax advisor is recommended, especially as European regulations like MiCA continue to take effect.

Conclusion

Navigating cryptocurrency taxation in Bulgaria relies on understanding a few fundamental rules. With a flat 10% tax rate on realized capital gains and a clear distinction between holding and disposing of digital assets, the framework is relatively straightforward. Ensuring accurate record-keeping of all trades, mining rewards, and deductible fees is essential for meeting the annual April 30 filing deadline. As regulations continue to evolve across Europe, maintaining detailed logs and seeking professional tax guidance for complex portfolios will help ensure full compliance with the National Revenue Agency.
